    • A process for making a replaceable socket having a body portion with a concave internal raceway and insertion slot structure to allow installation and removal of a spherical bearing and the replaceable socket made by that process. The process includes the steps of providing a mandrel; providing a removable core assembly that includes a cylindrical core axially truncated to have opposed arcuate surfaces conforming to the insertion slot structure and spaced apart ends, and a truncated spherical core having an open diametrically extending slot dimensioned to removably receive one of the cylindrical core ends therein when assembled and a spherical surface in conformity with the spherical bearing to be installed in the socket; mounting the core assembly on the mandrel; applying a parting agent to the core assembly; applying an overlayment onto the core assembly; applying a hardenable liquid to coat and bond the overlayment and fill any interstices that exist; hardening the liquid to form a unitary member having an outer surface; removing excess overlayment from the unitary member to provide the socket with a finished periphery and ends; removing the core assembly with the finished socket thereon from the mandrel; withdrawing the cylindrical core axially from one of the finished ends to expose the insertion slots in the socket; and rotating the truncated spherical core within the replaceable race and withdrawing same through the exposed insertion slots to expose the concave raceway within the socket.
    • 一种用于制造具有主体部分的可更换插座的方法,该主体部分具有凹入的内滚道和插槽结构,以允许安装和拆卸球形轴承以及由该工艺制成的可更换插座。 该方法包括提供心轴的步骤; 提供可移除的芯组件,其包括轴向截顶的圆柱形芯体,以具有与插入槽结构和间隔开的端部相符的相对的弧形表面,以及具有敞开的径向延伸的狭槽的截顶球形芯,其尺寸可移除地容纳其中一个圆柱形芯端 组装时,球面与球面轴承一致,安装在插座中; 将芯组件安装在心轴上; 将分离剂施加到芯组件上; 将覆盖层应用到芯组件上; 应用可硬化的液体来涂覆和粘合覆盖物并填充存在的任何间隙; 硬化液体以形成具有外表面的整体构件; 从整体构件上移除多余的叠层以为插座提供成品周边并结束; 从芯轴上将其上的成品套筒移除芯组件; 从其中一个完成的端部轴向地退出圆柱形芯,以露出插座中的插槽; 并将截顶的球形芯旋转在可更换的座圈内并且通过暴露的插入槽将其退回,以露出插座内的凹槽。

    • The invention proposes a novel method for providing a covering pad member of silicone rubber to a frame of spectacles on the portions coming into contact with the human body of the wearer of the spectacles, such as the side pieces and the nose pads. According to the inventive method, a shaped member of the silicone rubber having dimensions somewhat smaller than the portion to be covered therewith is first swelled with an orgnosilicon compound having volatility, inserted to the portion, e.g. sidepiece, and then dried by evaporation of the organosilicon compound as the swelling agent whereby the member shrinks to fit the portion of the frame tightly. Organosilicon compounds, e.g. hexamethyldisiloxane, are recommended owing to the physiological inertness to human body as well as owing to the absence of aggressiveness to the plastic part used in the frames of spectacles causing no damage to the beautiful appearance of the frame even in an inadvertent contact.
    • 本发明提出了一种新颖的方法,用于在与眼镜的穿戴者的人体(例如侧片和鼻垫)接触的部分上将眼镜的框架提供硅橡胶的覆盖垫部件。 根据本发明的方法,硅橡胶的成形构件的尺寸略小于要被其覆盖的部分的尺寸,首先用具有挥发性的硅氧烷化合物膨胀,插入到该部分中。 然后通过蒸发有机硅化合物作为溶胀剂干燥,由此部件收缩以紧紧地装配框架的该部分。 有机硅化合物,例如 推荐使用六甲基二硅氧烷,因为对人体的生理惰性以及由于对眼镜架中使用的塑料部件没有侵蚀性,即使在无意的接触中也不会损坏框架的美丽外观。
